FLUID SPREADER Ult MAEKENG DEVICE.

Application filed. @ctober 4:, 1921. Serial No. course.

To aZZ whom it may concern:

Be it known that l, REGINALD Euro 01.- nnnnnsnxw, a subject of the Kingof England, residing at London, England, have invented certain new anduseful Improvements in Fluid Spreaders or Markin Devices, of which thefollowing is a speci cation.

llhis invention consists in improvements in or relating to fluidspreaders or markingdevices and refers particularly to spreaders for usewith adhesives such as gum or to marking-devices for use with ink orfluids containing pigments.

An object of the invention is to afiord' a construction in which asimple, handy fluid container has spreading means combined with it.

According to the present invention such a device comprises incombination a tubular container having a closed end and perforations inits lateral wall in the region of that end, and a flexible member whichis resiliently held against the outer Wall of the container to coverover the orifices therein, which projects beyond the closed end of thecontainer, and which has preferably an irregularly formed or slitted endsurface. Alternatively the end surface may be smooth.

Where reference is made herein and the context does not otherwiseprovide, the term irregularly formed end surface as applied to theflexible member, is to be understood to include any irregular formationor slitting of the end of the tube or the application thereto of artssuch as bristles which grill give the e ect of an irregular end surace.

The purpose of the flexible member is normally to serve as a valve toclose the oridoes; but when its free edge is drawn in contact over thesurface on to which the fluid is to be spread the member is drawn awayto uncover the orifices and to allow the fluid to pass down on to thesurface over which it is spread by the member itself.

Conveniently, the flexible member is in the form of an elastic tube,sprung over the perforated end of the container; and in a preferredconstruction the perforated end portion of the container is an innertubular part which is separate from and fits within an open end of theouter tubular container and is provided With an elastic or. flexiblemember which serves to close the space be tween the inner and outertubular parts.

Some preferred forms of the invention will now be described in detail byway of example only with the aid of the accompanylng drawings in whichFigure 1 shows mainly a longitudinal sec tron of one form of the device,

gigure 2 shows in perspective the spreader 7 Figure 3 is a similar viewto Figure 1 of a modified form of device,-

Figure 4 shows in perspective a modified form of spreader,

Figure 5 is a sectional view of the end of the device with a modifiedform of spreader.

Figure 6 is a part sectional view showing a further modification in theform of spreader, and Y Figure 7 is a view similar to Figure 6 showing amodified form of the tubular end portion of the spreader.

Like reference numerals indicate like parts in several figures of thedrawings.

In the construction shown in Figures 1 and 2 the container may be madeof any a convenient material, such for example as metal or vulcanite andcomprises primarily an open-ended container tube 1 of any convenientdimensions. One end of the tube is closed by a rubber or other plug 2andsan end cap 3 and this end can thus, serve as the charging endthrough which the fluid can be introduced.

lhe other end of the container 1 is tapered by shouldering as shown andwithin it is inserted a short length of tube a of smaller diameter thanthe tapered end of the container tube 1 through which it is in sorted.The tube a is closed at its outer end and has perforations 5 in itslateral wall close to the closed end. Over the tube 4 is sprun a shortlength of rubber tube 6 which W1 1 cover over the orifices 5 and projectslightly beyond the closed end of the tube 4c. The rubber tube 6 and thetube 4: can be forced together into the open end of the container tube 1and thereby close the latter.

The outer circular edge of the rubber tube 6 is preferably slitted bymeans or radial slits 7 shown clearly in Figure 2. Alternatively, asshown in Figure 4;, the outer circular end of the rubber tube 8 may beformed with serrations 8 and either the slitted or serrated edge servesto aid in the spreading of fluid ever a surface to which the latter isto be applied.

The main container tube preferably provided with an air-inlet orificenear that end of it which is closed by the. plug 2 so as to permit thecontained fluid to flow readily towards the opposite end. In the formshown the plug 2 is formed with an axial orifice 9 and the cap 3 isalsoformed with an orifice 10. The cap 11 for the front end, which at timesis put over the back end, has a central orifice 12 adaptedfor aligningwith the orifice 10.

In the modified construction shown in Figure 3 the container-tube 1 isclosed at one end with a rubber or other plug 2 which is covered bymeans of a cap but in this case there are no axial perforations similarto the perforations 9 and 10 of Figure 1. In the wall of thecontainer-tube 1 is an orifice 13 and in the plug 2 is a groove or slot14 extending to an opening at the inner end of the plug. Normally theslot 14 and orifice 13 are maintained out of register but when it isdesired to use the device the plugfi can be rotated by turning the cap 3(which can be knurled or fluted to give ones fingers good grip) to bringthe slot 14 into register with the orifice 13, thus permitting air toenter the-back end of the containertube 1. The other or front end of thecontainer 1 is not reduced in diameter as in the previous example but asbefore, there is inserted in it a tube 4 having orifices 5 with a rubberor other resilient tube 6 closing the space between the tube 4 and thewall of the container tube 1. In this exam 1e the outer end of therubber or flexible tulle 6 is smooth, that is to say, it is not slittedor serrated.

In place of the rubber plug 2- a screw plug could be provided of anyconvenient material or a plain plug may be provided of material otherthan rubber.

In use it is found that the natural resilience of the rubber or similartube 6 is sufiicient to close the orifices 5 under normal condltions,but if the projecting edge of the tube 6 is drawn in contact over asurface, one side of the tube will be dragged away from the tube 4thereby uncovering some of the orifices and allowing contained fluid toflow out from the container through the orifices 5 on to the surface.The free edge of the tube 6 serves to smear the fluid over the surfaceand it is found that slits such as 7, or serrations such as 8, serve toaid in the even smearing of the fluid over the surface. i

It is' found that for certain fluids, such for example asink, the slitsor serrations are unnecessary and a tube having a smooth end such as isshown in Figure 3 is quite i satisfactory.

In the modification illustrated in Figure 5-- nstead of the rubber tube6 being formed with a slltted, serrated or plain end, it is providedwith a plurality of groups of bris tles 15 or like independent bodies ofother preferred material, as shown, the ends of which are let into thematerial of the rubber and are held in place by securing-wires 16. Thusthe contents of the container 4 will flow as before to the orifices 5and will escape therefrom when the bristles are moved over in contactwith the surface to be coated, thus slightly drawing the material of thetube 6 away from the orifices. The bristles then serve to apply thefluid to the surface.

This construction is found to have great utility, for example instencilling, or for application of colouring matter; although it is tobe understood that the bristles may be employed when other fluids are tobe used.

Figure 6 illustrates a construction of spreader in which the tubularcontainer 1 is formed with an end portion 17 of reduced diameter. Thisend portion is screw-threaded into the body of the container 1, in orderthat it may be readily removed therefrom when desired. In this case thelateral apertures 5 are formed in the reduced end portion 17 in theregion of the closed extremity of the latter. The tubular elastic member6 which fits-over the reduced end portion 17 of the container istaper-ended as shown, the bore of the member 6 at its outer extremitybeing equal to the width of the line which the device is required tomake when used as a marker. The extremity of the tapered end is serratedas in the previous examples.

In Figure 7 the construction of the end portion of the container is"exactly the same as in the example illustrated in Figure 6. In thiscase, however, the tubular elastic member is not taper ended.

The invention includes any flexible memher for covering the outletorifices of the device provided that the member is such or is soresiliently held as normally to serve as a valve to close the orificesbut to be capable of being moved away therefrom when its free edge isdragged over the surface upon which the fluid is to be spread.
